Above commit added "SSB = y" dependency to the wrong symbol SSB_DRIVER_PCICORE_POSSIBLE and prevented SSB_DRIVER_PCICORE from being selected when needed. PCI core driver for core running in clienthost mode is important for bus initialization. It's perfectly valid scenario to have ssb built as module and use it with buses on PCI cards.

platform, which uses PCI_DRIVERS_GENERIC instead of PCI_DRIVERS_LEGACY,
various files in drivers/ssb/ have failed to build.
